Though SC did not say so in open words, this is the meaning of this judgement.
This is a landmark judgement by Supreme Court.
Now even a neighbor can file complaint to police that Husband living in next house is beating his wife.
Common perception is such that only “Wife” can file complaint of 498A IPC.
Supreme Court says that if any police officer finds that you are ill treating your wife, then without permission of your wife, even police officer can file complaint under 498A of IPC and can punish you through court.
Moral: Don’t ill-treat wife. Adjust with her. Respect and fear her.
